If you'd like to use a 3rd party plugin with the native WP gallery option, this customization is going to be up to you. If you are having issues, you'll need to reach out to the 3rd party plugin author since this is not included or advertised in the theme. Note: this plugin has not been updated in over 2 years: https://wordpress.org/plugins/jquery-colorbox/
